RABBLE-CARFRIAG E.

SPECIFICATION forming part of Letters Patent No. 706,755, dated August 12, 1902. Application tiled August 2, 1901. Serial No. 70,643. (No model.)

To all whom it may concern:

Be it known that I, DANIEL C. JACKLING, a 4citizen of the United States, residing at Republic, in the county of Ferry and State of Washington, have invented certain new and useful Improvements in Rabble-Carriages, of which the following is a specification.

This invention relates to that class of rabble-carriages which are adapted to be used in A further object is to provide 4a rabble-ear-` riage with means by which it may detachably supportrthe rabble-blades in operative position. Y

A further object of the inventionis to provide simple,ieconomical, and efficient mechanism by which the operating link belt mayv be easily connected to or disconnected from the rabble-carriage.

The invention consists principally in the combination of abodyportiou provided with a pair of bars extending longitudinally at each end thereof, a trolley-wheel rotatably mounted between each pair of bars, and means for detachably securing the rabble'mechanisin to the carriage.

The invention consists, further, in the combination of a body portion provided with a pair of bars extending longitudinally thereof; a pair of wheel washers secured in position between the ends of the pair ofibars to form a ball-raceway, an annular wheel-rim surrounding such washers and completing the racewaytand a plurality o f antifriction-balls interposed between the washers and wheelrim. Y.

The invention consists, further, in the combinationof a body portion provided with a pair of trolley-wheels, a laterally-projecting 5o tubular portion, a rabble-bar, and means for dctachably securing the rabble-bar to the tubular portion.

The invention consists, further, in the combination of a body portion provided with a pair of trolley-wheels, a laterally-extending arm provided with a recess, a sprocket-chain, and clip mechanism removably secured in such recess for attaching and detaching the sprocket-chain thereto.

The invention consists, furtherand finally, in the features, combinations, and details of coi'istruction hereinafter described and claimed.

In the art to which this invention relates it is well known that it is highly desirable to have a rabble-carriage and attached mechanisms of such construction and arrangement that the elements which go to form the entire combination of mechanisms may be attached to or removed from position with the least time and expense. To accomplish this end, my invention is principally designed.

In illustrating and describing these inventions, I have only illustrated and described that which I consider to be new-so far as these inventions are concerned-taken in connection with so much of the other mechanisms that go to form an ore-roasting furnace as will enable those skilled in the art to practice the same, leaving ont of consideration such other mechanisms as do not form any part or portion of this specific invention and which, if described or illustrated herein, would only 'tend to proliXity, confusion, and ambiguity.

In describing these improvements I will first describe the rabble-carriage proper. In this particular art it is desirable that a rabble-carriage be constructed and arranged so that the Wheels that go to form the antifriction devices upon which the mechanisms are carried may be held in operative position in such manner that they can be removed, renewed, or repaired, as seems desirable, and which are adapted to run Without the use of lubricant. To accomplish this result, I make a rabble-carriage havinga body portion d and provide it with a pair of longitudinal bars b, extending substantially parallel from each end thereof. Between the ends of each of these pair of parallel bars is inserted a pair of disk or Wheel washers c, held in position and in engagement with the parallel bars by means of bolt-and-nut mechanism (l. (Shown particularly in Fig. 13.) These Washers are constructed as shown in Fig. 13 and provide a raceway in Which a plurality of antifriction-balls e are inserted. To obtain the desired Width of the raceway, shims f are provided and may be used Whenever desired that, is, if the right Width can be obtained by the Washers alone the shims are not used; but if a Wider raceway be desired the desired number of shims are inserted. To complete the trolley-Wheels, an annular Wheel-rim gis provided, of the shape shown in Fig. 13, which completes the raceway and is mounted on the antifriction-balls, as shoWnso that in operation the Washers remain fixed, While the wheel-rim rotates on the antifriction-balls.

To provide forthe rabble mechanism by which the ore or material to be roasted is agitated, stirred, and moved along upon the hearth h of the furnace, a rabble-bar t' is provided, composed, preferably, of a tube or pipe, as shown particularly in Figs. 6 and 10.

need no further description here.

,shoulders in the pockets u.

Mounted upon this supporting-bar are a pl1i= rality of rabble-blades j, which are prefer-4 ably formed in tWo parts, having hub portions 7c, as shown particularly in Fig. 1l, Which are securely. held in position by means of the bolts Z. hub 7o is provided with a doWel-pin fm, arranged to enter a perforation or opening n in the supporting-bar, by Which the rabble-blade is prevented from turning or having any movement independent of the bar. To detachably hold these bars in position, the rabble-carriage is provided with a laterally-projecting arm 0, tubularshaped at the end thereof, the tubular portion being made in two parts, one part rigidly secured to the arm, and the other part, p, forming a cap, which may be removed or inserted in position at. Will. This cap is held in position by means of the bolts q. (Shown particularly in Fig. 9.) The rigid or immovable part of the tubular portion is provided with two dowels r, also arranged to enter the perforations n in the rabble-supporting bar and hold the bar from any movement independent of. the rabblecarriage.

As shown in Figs. 2 and 3, the rabble-blades are inclinedin other words, are arranged at an angle to their line of xnotion-one half of the rabble-blades, those to the left-side of the center, (see Fig. 2,) being inclined in one direction, while the blades on the other half of the bar or to the right of the center are inclined in an opposite manner.

In Fig. 4 the blades are shown inclined in an opposite direction from the blades shown in plan view in Fig. 2, the arrangement being such thatl the material is agitated-that is, thrown alternately to the side of the furnace and to the center thereof-asitis being pushed along. The supporting-bar is also provided with a number of pushers S, which, however, form no particular part of thisinvention and It is also desirable that some mechanism be provided by which the sprocket-chain that transmits the power and motion to the rabble-carriage may be easily and quickly attached or detached from the rabble-carriage. To accomplish this result, the rabble-carriage is provided With a second laterally-projecting arm if, containing a pocket or socket u in the upper surface thereof. Arranged in this pocket is a pair of clips e, T-shaped in plan view, so that the T-'heads thereof may contact the Each clip has arranged between the free ends thereof a block w, and all of the parts are perforated, as shown in Figs. 14, 15` and 1G, so that a pair of stove-bolts no may be passed therethrough to securely lock the clips in position. In Figs. 16 and 17 the clips are shown in position, each clip being connected to one end or link of the sprocket-chain y, so that when it is necessary to insert or remove a link in position or insert or remove a chain from the rabble-carriage all that is necessary to do is to remove One portion of the tubulary IOO IIO

the bolts ac, and thereby the chain, all of which can be done simply and economically.

In order to provide for the contraction and expansion of the bar, due to changes of temperature traveling in and out of the furnace, it will be seen that .one set of wheel-rimsthose shown to the left of Fig. l-is provided with flanges where they are mounted upon the tracks 20, while the wheel-rims to the right of such figure are not so provided, but are left, so far as the periphery thereof is concerned, in smooth cylindrical surfaces. In this way the right-hand side of the rabblesupporting mechanism may move laterally, so far as the carriage is concerned, and yet in no way interfere with the operations of the mechanisms.

I claim I. In a rabble-carriage of the class described, the combination of a body portion provided with a pair of bars extending longitudinally thereof, a pair of wheel washers secured in position between the ends of the pair of bars to form a ball-raceway, an'annular wheel-rim surrounding such washers and completing the raceway, and a plurality of antifriction balls interposed between the washer and wheel-rim, substantially as described.

2. In a rabble carriage of the class described, the combination of a body portion provided with a pair of longitudinal bars, a pair of trolley-wheels mounted between the ends of the longitudinal bars, a laterally-projecting tubular portion made in two parts, means for clamping such parts together, and a rabble-bar secured in such clamping tubular portion, substantially as described.

3. In a rabble-carriage of the class described, the combination of `a body portion provided with a pair of longitudinal bars, a pair of trolley-wheels-one mounted between each end of the longitudinal bars, alaterallyprojecting tubular portion made in two parts extending inwardly from such carriage, means for clamping such parts together, a tubular rabble-bar mounted inthe clamping portions of the carriage, and rabble-blades secured to such tubular bar extending upwardly and downwardly therefrom and at an angle to their line of motion, substantially as described.

4. In a rabble -carriage of the class described, the combination of a body portion provided with a pair of longitudinal bars,

movable and one fixed, bolt-and-nut mechanism for securing such parts together, a tubular rabble-bar, rabble-blades on such tubular rabble-bar extending upwardly and downwardly therefrom and provided with a cylindrical hub portion, and dowel mechanism for securing the rabble-carriage and rab\ ble-blades to the tubular bar so as to prevent their having independent motions, substantially as described.

5. In a rabblecarriage of the class described, the combination of a body portion provided with trolley-wheels, an outwardly and laterally extending arm provided with a recess, a sprocket-chain, and clip mechanism removably secured in such recess for attaching and detaching the sprocket-chain thereto and therefrom, substantially as described.

6. In a rabble -carriage of the class described, the combination of a body portion provided with trolley-wheels, laterally -extending arms forming a part thereof and extending outwardly therefrom provided with a shouldered recess in one surface thereof, a sprocket-chain, a pair of T-shaped clips removably secured in such recess, a block interposed between the ends of each clip, and bolt-and-nut mechanism for securing the clips and laterally-projecting armof the rabblecarriage together, substantially as described.

7. In a rabble -carriage of the class described, the combination of a body portion provided with apair of flanged trolley-wheels, a bar detachably secured thereto and provided with a plurality of rabble-blades, a second carriage provided with a pair of trolley-` wheels having smooth peripheral cylindrical surfaces to permit expansion and contraction of the tubular bar, a laterally-projecting tubular portion on each of Vsuch body portions made in two clamping partsone movable and one fixed-on which the rabble-bars are detachably secured, and bolt-and-nut mechanism for securing such parts together substantially as described.
